Configure Access Point (Hotpots)

By default when flashing the firmware after ESP8266 WiFi configured as a AP mode in the WiFI AP SSID name of Mongoose_?????  here ????  is the chip id and password is Mongoose .

FAQ

• How to Set ESP8266 to AP mode?
• How to Set ESP8266 as Hotpots?

Steps to follow

• Go to the Device files tab in a web browser using the mos tool. (IP address http://127.0.0.1:1992/#files )
• Change the ap credential or set the credential in the conf0.json  file. (Refer Below Image)

Code Example

• Enable AP Mode : “enable”: true, .
• Disable AP Mode : “enable”: false, .
• You can hide ESP8266 AP mode list using “hidden”: false,  (Not shown WiFi available list).

const wifiConfig = {
  wifi: {
    ap: {
      enable: true,
      ssid: "ArunEworld",
      pass: "info@aruneworld.com",
      hidden: false,
      channel: 6,
      max_connections: 10,
      ip: "192.168.4.1",
      netmask: "255.255.255.0",
      gw: "192.168.4.1",
      dhcp_start: "192.168.4.2",
      dhcp_end: "192.168.4.100",
      trigger_on_gpio: -1,
      disable_after: 0,
      hostname: "",
      keep_enabled: true
    }
  }
};

ESP8266 connects to WiFi Router

Here’s an example code snippet to connect an ESP8266 to a WiFi router using Mongoose OS:

load('api_config.js');     // Load the Mongoose OS configuration API
load('api_net.js');        // Load the Mongoose OS network API

// Configure WiFi settings
let ssid = 'YourWiFiSSID'; // Replace 'YourWiFiSSID' with your WiFi network SSID
let password = 'YourWiFiPassword'; // Replace 'YourWiFiPassword' with your WiFi network password

// Connect to WiFi
Net.connect({
  ssid: ssid,
  pass: password,
  auth: Net.AUTH_WPA2_PSK // Use WPA2 authentication (change if necessary)
});

// Event handler for WiFi connection status change
Net.setStatusEventHandler(function(ev, arg) {
  if (ev === Net.STATUS_DISCONNECTED) {
    print('WiFi disconnected');
  } else if (ev === Net.STATUS_CONNECTING) {
    print('WiFi connecting...');
  } else if (ev === Net.STATUS_CONNECTED) {
    print('WiFi connected');
  }
});

Replace 'YourWiFiSSID' with the SSID of your WiFi network and 'YourWiFiPassword' with the password of your WiFi network. This code will attempt to connect the ESP8266 to the specified WiFi network using the provided credentials. It also includes event handlers to print status messages when the WiFi connection status changes.
